Hunter (hamstring) is set to pitch in an extended spring game Saturday, Matt Gelb of The Athletic Philadelphia reports.
Hunter is expected to be ready to return after making a pair of rehab appearances, leaving him eligible to return sometime next week. When he arrives in Philadelphia, he'll assume a role as a setup man in front of Hector Neris. Neris' closer role isn't under any immediate threat, though he does have a 7.71 ERA through his first five appearances.
